Automatic Transmission Fluid

Synthetic Automatic Transmission Fluid
Improves fuel efficiency, reduces transmission temperatures and increases
transmission life. Provides unsurpassed thermal stability and up to
five times the service life of conventional ATFs. Delivers maximum
protection for towing and other severe-duty applications.

Use where ATF is recommended in Mobile
or Stationary Hydraulic and Power Steering units.

As
automatic transmissions have become increasingly complex, the performance
requirements of transmission fluids have increased. Reduced fluid sump
volumes, continuously slipping torque converter clutches, six-speed
transmissions and increased power densities significantly increase the
level of stress put on a lubricant. In response, General Motors recently
introduced a higher quality factory fill ATF, and in order to ensure their
transmissions continue to receive adequate protection, they have upgraded
their DEXRON®-III specification for service fill transmission fluids.

“If we look at the kinds of fluids that are being blended out in the
marketplace some of them are a long way away in terms of performance from
our current factory fill, because they are still based on blends that had
been formulated a number of years earlier,” said GM Transmission Fluid
Group Leader Roy Fewkes. “The objective of the DEXRON® specification is
to make sure that GM customers, wherever they are in the world, have a
fluid that is appropriate for their transmission. So there was a need for
us to upgrade the specification in order to make sure that the service
fill fluids in the market are more representative of the factory fill
performance that the transmission has been designed for.”

To ensure protection for transmissions with reduced sump volumes and
higher operating temperatures, the new DEXRON®-III specification requires
a longer Oxidation Test. Fluids are now required to maintain performance
for 450 hours, up from 300. GM expects the new oxidation requirements will
be the most difficult for lubricant manufacturers to meet. In addition,
DEXRON®-III calls for quicker de-aeration times to accommodate smaller
sump volumes.

Because today’s transmissions must handle increased torque and
transmit more power, thermal stability is crucial for DEXRON®-III fluids.
The combination of higher operating temperatures and reduced oil volumes
calls for fluids that can not only maintain performance at higher
temperatures, but also for longer periods of time.

Electronically controlled converter clutches, implemented to improve
transmission efficiency and fuel economy, are sensitive to the frictional
properties of lubricants. Because friction modifiers are adversely
affected by increased temperatures and fluid oxidation, GM introduced a
new EC3 Low Speed Friction Test to ensure friction performance is
maintained for as long as possible.

The increased quality standards of the new DEXRON®-III specification
could signal the end of Group I base stock use in ATF formulations. “The
basic additive performance will essentially remain the same and people
will have to adjust formulation in order to get them past things like the
Oxidation Test,” says Fewkes. “But essentially what it {the new DEXRON®-III
specification} is doing is driving the formulations away from Group I
towards Group II base stocks.”

AMSOIL Synthetic Automatic Transmission Fluid (ATF) exceeds the
requirements of the new DEXRON®- III transmission fluid specification. It
resists thermal and oxidative degradation up to three times longer than
conventional fluids and twice as long as the new 450-hour DEXRON®-III
test requirement. It protects clutches, planetary gears, valves, pumps and
seals from damaging sludge and varnish deposits and ensures cool, smooth
transmission operation for intervals up to three times longer than
recommended by the vehicle manufacturer.

AMSOIL
ATF provides smooth shifting and
long, trouble-free transmission life. In addition, the anti-wear additive
package makes AMSOIL
ATF an excellent lubricant in other hydraulic
systems. In tests designed to measure wear characteristics under severe
service and high pressure operating conditions, AMSOIL
ATF far exceeds the
requirements of hydraulic equipment manufacturers.

Extended Drain Intervals

AMSOIL
ATF is formulated for extended drain
intervals. Transmissions usually operate under severe service conditions.
They are subjected to extensive idling, frequent short trips, cold
temperature driving, sustained hot weather driving or trailer towing. When
conventional transmission fluid is used, it should be changed every 15,000
to 30,000 miles. AMSOIL
ATF should be changed at intervals up to three
times longer than the recommendations of the vehicle manufacturer.

APPLICATIONS

AMSOIL
Synthetics Automatic Transmission
Fluid is completely compatible with other synthetic and petroleum
automatic transmission fluids. AMSOIL
ATF is a universal, multifunctional
fluid and greatly reduces the need for specialized fluid inventories and
the possibilities of misapplication.

SERVICE LIFE

AMSOIL
ATF has an expected fluid life of
three times the automatic transmission manufacturer's recommendations.
Drain intervals may be extended indefinitely when fluid analysis is used.

AMSOIL ATF Maximizes Automatic
Transmission Efficiency and Life

Over 40 percent of total energy loss in an automatic transmission can be attributed to the act of pumping
automatic transmission fluid to the transmission's working components during transfer of power. The mechanical efficiency of an
automatic transmission is directly affected by the viscosity of the transmission fluid. When
temperatures drop and cause ATF to thicken, transmission efficiency and power decline.
Industry tests on torque loss demonstrate that a temperature increase of 150 degrees F increases transmission efficiency by up to 37.5 percent. In other
words, as viscosity decreases, transmission efficiency increases.

Wear Protection
AMSOIL
Synthetic Power shift Transmission Fluids exceed the wear
requirements of the Caterpillar TO-4 specification. AMSOIL
Synthetic Power shift Transmission Fluids are formulated without viscosity index
improvers for superior shear stability. They maintain grade throughout
service life, due to their superior shear stability, providing long-term
protection against equipment wear, even when equipment is frequently
subjected to sustained periods of applied pressure or high horsepower and
high torque.

High and Low Temperature Performance
In high temperatures, AMSOIL
Synthetic Power shift Transmission Fluids
dependably protect components from wear. Their superior oxidative and
thermal stability inhibits the formation of varnish, deposits and sludge
so equipment runs clean. AMSOIL
Synthetic Power shift Transmission Fluids
are excellent heat transfer fluids and may help hot-running equipment
operate up to 50°F cooler and keep them running in their optimal
temperature range. In low temperatures, AMSOIL
Synthetic Power shift Transmission Fluids flow readily for dependable startup and post-startup
protection.

Copper Corrosion, Rust and Foam
Inhibition
AMSOIL
Synthetic Power shift Transmission Fluids protect equipment from
copper corrosion and rust, even during equipment storage. AMSOIL
Synthetic Power shift Trans- mission Fluids do not foam in service, protecting
equipment from the metal-to-metal contact and wear that occurs with use of
foam-filled fluids.

Installation
AMSOIL
Synthetic Power shift Transmission Fluids are fully compatible with
other fluids used in power shift applications. To install AMSOIL
Synthetic Power shift Transmission Fluids, drain the fluid in the system,, replace
the filter (if so equipped) and install the appropriate AMSOIL
Synthetic Power shift Transmission Fluid.

Service Life
AMSOIL
Synthetic Power shift Transmission Fluids provide two to five times
the service life of conventional petroleum fluids if AMSOIL
Synthetic Power shift Transmission Fluids are kept free of dirt and moisture.

AMSOIL
Synthetic Power shift Transmission
Fluids may be used for 250,000 miles or five years (whichever comes first)
in manual transmissions.

Wear Protection
Synthetic Super shift contains a robust additive system for extra
protection, and its shear stable base oils prevent viscosity
loss throughout its service life. Super shift provides long-term
protection against equipment wear, even when the equipment is
frequently subjected to sustained periods of applied pressure or
high horsepower and high torque. Clutches, bearings and bushings
last longer, saving money on transmission repairs.

Copper Corrosion,
Rust and Foam Inhibition
AMSOIL Synthetic Super shift Racing Transmission Fluid protects
equipment from copper corrosion and rust, even during equipment
storage. It does not foam in service, protecting equipment from
the metal-to-metal contact and wear that occurs with use of
foam-filled fluids.

COMPATIBILITY
AMSOIL
Synthetic Super shift Racing Transmission Fluid is fully
compatible with other fluids. However, a mixture of AMSOIL
Super shift and another oil will decrease performance and offer a
shorter service life than pure AMSOIL
Synthetic Super shift
Racing Transmission Fluid.

RECOMMENDATIONS
AMSOIL
Super Shift Racing Transmission Fluid is recommended for
automatic transmissions that are coupled to high horsepower,
high torque engines. It is also recommended where heavy loads
place a high demand on transmissions. Recommended where CAT
TO-4, Allison C-4 or Ford Type F is required. Suggested
automatic transmission applications:

Note: AMSOIL
Super Shift Transmission Fluid is NOT recommended as a replacement for Ford Mercon, GM Dexron or
Chrysler ATF+ type fluids in passenger vehicles and truck
transmissions as it may cause erratic shift patterns, chattering
or noise. AMSOIL
is not responsible for transmission performance
inconsistent with those specifications listed, where no
modifications have been made from the original manufacturer’s
design.
